Sighting #1: I was at the airport, checking in at the gate, when the airport employee asked "Has anyone put anything in your baggage without your knowledge?" I said, "If it was without my knowledge, how would I know?" He smiled and nodded knowingly, "That's why we ask."
Sighting #2: The stoplight on the corner buzzes when it is safe to cross the street. I was crossing with an intellectually challenged co-worker of mine, when she asked if I knew what the buzzer was for. I explained that it signals to blind people when the light is red. She responded, appalled, "What on earth are blind people doing driving?"
Sighting #3: I worked with an individual who plugged her power strip back into itself and for the life of her could not understand why her system would not turn on.
Sighting #4 (a rare "double sighting"): A friend had a brilliant idea for saving disk space. He thought if he put all his Microsoft Word documents into a tiny font they'd take up less room. When he told me I was with another friend. She thought it was a good idea too.
Sighting #5 (from Tech Support):
Tech Support: "How much free space do you have on your hard drive?"
Individual: "Well, my wife likes to get up there on that Internet, and she downloaded ten hours of free space. Is that enough?"
Sighting #6 (from Tech Support):
Individual: Now what do I do?
Tech Support: What is the prompt on the screen?
Individual: It's asking for "Enter Your Last Name."
Tech Support: Okay, so type in your last name.
Individual: How do you spell that?
